GK Series

Industrial Ultrafiltration Elements – TFM* 3,500 MWCO

The G-Series family of proprietary thin-film ultrafiltra-

tion membrane elements is characterized by a molec-

ular weight cutoff of 3,500 on polyethylene glycol and

a smooth, fouling resistant membrane surface.

GK Elements are used for surface water pretreatment,

color/TOC reduction, and chemical purification.

²These elements are dried then bagged before shipping.

The element diameter (dimension C) is designed for optimum performance in GE

pressure vessels. Others pressure vessel dimension and tolerance may result in

excessive bypass and loss of capacity.
